PHP 7.2 to 7.3

[Anna Barley]

I'm changed PHP 7.2 to 7.3 and after my all website down. I asked about my website hosting company, they told my websites are not compatible PHP 7.3. But I haven't found the issue when I changed the 7.1 to 7.2. How to fix that isse?

It is very hard to know what exactly is causing the problem without seeing the actual PHP code in question, however you are most likely using depreciated statements which are no longer supported in 7.3 version. The most simple and logical solution would be reverting back to version 7.2 for which you said is working fine, there should be no differences in performance between 7.2 or 7.3

Just roll back.
Most probably you will not notice the difference in performance.

Agree it’s easier to roll back.

Or if you really want to keep 7.3, what CMS are your sites running on?

Enable logging to see where the issue is. 7.2 to 7.3 should not cause anything usually (I have migrated successfully from 7.0.1x to 7.3) with no problems multiple times.
Enable loggings and see if there is any errors. (I would not mind helping you out, send me a PM with the erros or whatever you have and I can try hleping.)

You can find a list of backward incompatible changes between PHP 7.2 and 7.3 on the PHP website (can't link it due to my post count). Generally, you'll find it's probably the HEREDOC change. At least that will be the most prevalent issue. But, as mentioned, we really cannot help you debug this without errors. Check for a local error_log file, and share the contents of that with us.

I always avoid updating anything when its still out of box. I wait and wait and wait to save myself a lot of headache.

After years in coding and programming arena I have learnt one golden rule "If it's not broken, DON'T fix it"
